All 50 Dreamliner jets have been grounded for the past two months after two separate incidents of battery fire, on a Japan Airlines flight at Logan airport in Boston and on an All Nippon Airways flight in Japan.

Since the grounding of the fleet in January, the Japanese airline has cancelled more than 3,600 flights to the end of May.

Reuters' source noted that compensation talks with Boeing had not yet begun, while a company spokesperson told the agency that it has not reached a decision regarding future talks with Boeing.

Boeing is yet to specify how it will compensate the airlines for lost revenue from the grounding of Dreamliners. Allowing a discount on future aircraft purchases would be beneficial for Boeing, as it allows the spreading of reimbursement costs over several years.

However, most of the airlines are expected to seek cash compensation, as they look for some quick money to make up their losses.

ANA's rival Japan Airlines (JAL) is the second-largest operator of Dreamliners, with seven aircraft in service and another 38 on order. United Airlines and Air India both own six each.

ANA previously said that it was losing $868,300 (£575,489, €674,582) in revenue per plane in the last two weeks of January. Meanwhile, JAL is expected lose 1.1bn yen ($11.6m) out of its operating profit for April-May, taking the total loss since the grounding to 1.8bn yen.
